This retrospective study investigated whether volumetric visceral adipose tissue (VAT) features that were extracted using radiomics and three-dimensional convolutional neural network (3D-CNN) approaches are effective when differentiating Crohn’s disease (CD) and ulcerative colitis (UC). The authors concluded that VAT-based deep learning and radiomics features were able to achieve fair accuracy in differentiating CD from UC.

Key points

  • High-output feature data extracted from volumetric visceral adipose tissue on CT enterography had an effective diagnostic performance for differentiating Crohn’s disease from ulcerative colitis.
  • With adjustment of clinical covariates that cause difference in volumetric visceral adipose tissue, adjusted clinical machine learning model reached stronger performance when distinguishing Crohn’s disease patients from ulcerative colitis patients.
